I flipped my bunny over today to inspect and possibly trim his nails and I saw this for the first time. I've had dogs in the past get cancerous lumps so that is what I'm worried about. It is located above and a bit to the right of his testicles
Though knowing my luck this is actually his member and I'm just seeing it for the first time.
